Dozens of Cardiff Heights residents are set to soon call New Lambton Heights home after Lake Macquarie council endorsed changing the two suburbs' boundaries.
The adjustment, first proposed by residents of Currawong Road in late 2016, was voted on at Monday night's ordinary meeting.
The meeting was held despite the increasing restrictions on public life amid the coronavirus outbreak.
Only seven of 12 councillors and the mayor attended and council staff were positioned in isolated seats around the chamber. One councillor also left early.
The council voted (5-2) to approve a motion which recommended adjusting the suburb boundaries to have properties in Currawong Road included within New Lambton Heights.
Currawong Road runs parallel to Main Road in Cardiff Heights, but has vehicle access from its eastern end only where it intersects with Marshall Street, which is in New Lambton Heights.
The council's approval of the suburb switch is a backflip on a decision it made in March last year to withdraw support for the proposal.
It pulled its support for the move at that time after a staff report found there was "no substantial or significant benefits in changing".
But the Geographical Names Board of NSW, the authority which ultimately approves suburb boundary adjustments, asked council to reconsider the matter after receiving six submissions advocating for adjustment following council's decision last March.
The council conducted a door knock of properties in Currawong Road late last year to gauge the number of owners in support or against the proposal.
It prompted 28 submissions, which were added to the six submissions sent to the Geographical Names Board to yield a total of 34 submissions from 44 affected properties.
Of the 34 submissions, 26 were in favour of the proposal and eight were against it.
The Geographical Names Board will now likely adjust the boundaries after council's endorsement.
